Insights
Postoperative cardiac arrhythmias, particularly atrial fibrillation, are common after large bowel resection. Older patients and those with hypertension face higher risks, and arrhythmias correlate with other complications.
Area of Science:
- Cardiology
- Colorectal Surgery
- Critical Care Medicine
Background:
- Postoperative cardiac arrhythmias are a significant concern in patients undergoing major surgery.
- Elective large bowel resection is associated with various perioperative risks.
Purpose of the Study:
- To investigate the incidence of postoperative cardiac arrhythmias in patients undergoing elective large bowel resection.
- To identify clinical factors associated with the development of these arrhythmias.
Main Methods:
- Prospective observational study of 51 patients undergoing elective open colorectal resection.
- Daily three-lead electrocardiograms were performed postoperatively.
- Data on risk factors and complications were systematically collected.
Main Results:
- The incidence of postoperative arrhythmia was 26% (13 patients), with atrial fibrillation being most common.
- Significant correlates included older age, hypertension, pre-operative and postoperative potassium levels, and postoperative pulmonary edema.
- Patients with arrhythmias had a higher likelihood of other postoperative complications.
Conclusions:
- Cardiac arrhythmias are frequent following elective large bowel resection.
- Older age and hypertension are key risk factors.
- The occurrence of arrhythmias is linked to an increased risk of other postoperative complications.
Objective:
To determine the incidence and clinical correlates of postoperative cardiac arrhythmias in patients undergoing elective large bowel resection.
Methods:
Fifty-one consecutive patients undergoing elective open colorectal resection were recruited for this prospective observational study. Participating patients underwent daily three-lead electrocardiograms postoperatively. Data regarding potential risk factors for arrhythmias were recorded. Post-operative complications were recorded.
Results:
Thirteen (26%) patients developed a postoperative arrhythmia, most commonly atrial fibrillation. Significant univariate correlates with postoperative arrhythmias were: age (P<0.01), hypertension (P<0.01), pre-operative serum potassium levels (P<0.01), postoperative pulmonary oedema (P=0.03), postoperative serum potassium (P=0.03) and sodium (P<0.01). Arrhythmia patients were more likely to have other complications (P=0.02). Thirty-one percent of arrhythmia patients had underlying sepsis compared with 18% of controls (P=0.38).
Conclusion:
Arrhythmias are common following elective large bowel resection. They occur in older patients and are associated with the development of other complications.
